Analysis of information sources in references of the Wikipedia article "Guillermo Hayden Wright" in English language version.
The identity of the 1900 US polo player named Wright is not certain. We believe he is the William Hayden Wright who won the 1898-99 Paris International and the Paris Open, but some sources have him listed as Guillermo Wright, not too surprising as the rest of his 1900 polo team was Mexican. Some French sources list him as J. H. Wright, who may be either James Hayden Wright, a Boston architect who lived in Paris in 1900, or John Harvey Wright, an American living in Pau in the south of France, who was an amateur jockey and known to be a polo player. A J. H. Wright played in the Paris Cup tournament in 1898 at the Bagatelle Polo Club in Paris, but further information is lacking.
